Christine tilts her head as Kira speaks, an expression of faint puzzlement on her face. She takes a breath to say something, but is distracted by the doorbell.
More than distracted - she picks up the note of the bell, humming it, then weaving a little melody around it. Minor third, fifth, octave, above, below, her fingers twitching slightly. Then, back to the tune she's been humming off and on ever since she arrived, but this time she gives quiet voice to the lyric:
"...all the pretty birds fly around my town... they try their best to please... it's not nice to spite happy appetite... the darkness comes to eat me... don't say you'll ever leave me... you will comfort... and appease me... you will build a nest for me... in a high and brittle tree... in a high and bending tree..."
